The Hata are mentioned by name more often than almost any other immigrant clan in the Nihonshoki, one of Heian-period Japan's epics, combining mythology and history.
The first leader of the Hata to arrive in Japan, Uzumasa-no-Kimi-Sukune, arrived during the reign of Emperor Chūai, in the 2nd century CE. According to the epic, he and his followers were greeted warmly, and Uzumasa was granted a high government position.
Roughly one hundred years later, during the reign of Emperor Ōjin, a Hata prince called Yuzuki no Kimi visited Japan from the Kingdom of Baekje in Korea. He said he had come from Baekje, and he wanted to emigrate to Japan, but that Silla would not permit him to do so. So 120 persons of his clan were staying at Minama. Having enjoyed his experience, he left Japan and returned with members of his clan "from 120 districts of his own land", as well as a massive hoard of treasures, including jewels, exotic textiles, and silver and gold, which were presented to the Emperor as a gift.
